Asindicated :in -.-the several views in the draw mg, ithe iband 1501 is SO LPIOPOIfiOHGd that thel a. .suflicient length .of the full width portion of theband between the .end of .the slot ill and the beginning .of the tongue :15 'tocompletely cross otter the .gap originally presented between the feet H .andCtB so that the ihosewithin the en circling :band M) will :be retained in substantial!- ly its :true cylindrical shape. having the tongue 1:5 come through the slot M and be carried loveewthe outside zofthe .pressure 'member ill, and thence through :the slot la and -under pressure member Ml, when the ,feet H and 18 are drawn .one toward the other in the clamping action, the pressure member 11 will ib'enrged against, the outer :I-ace of the wide portion of the band ill-with :a sliding action thereover and with frietional engagement between that portion of the tongue 15 which laps :over- .the pressure member I! .up ito-ithevslot M. iFFrQm that slot, the remaining- ..end portion .of the tongue 5 will :itself be :pressed against the outer surface of the band cavity thereunder having a. depth slightly less I0, into frictional engagement therewith so that the shoulder produced in the tongue l5 at the offset where the tongue passes through the slot l9 will not .be permitted to slip out of the abutment with the edge of the slot. Therefore it is to be seen that there is a multiplicity of holding area's set up in this particular form of terminal bracket I6. While normally the bracket I6 may remain a separate part from the tongue 15, it may be desirable in some installations to have the bracket 16 tacked to the tongue l5 by any suitable means, such as by spot welding, so as'to save timein the assembling of the clamp with the hose. Full clamping strength may be exerted, however, in the absence of such welding. For any particular size of clamp, the slot I4 will have a length such that the tongue I5, in passing therethrough, will be spaced from the ends of that slot i4 without causing the tongue to bend over such ends or be distorted from the circumferential form corresponding to the circumference of the,

forming a tongue; said band and tongue beingrolled and lapped upon itself to have the tongue carried through from the inside to the outside of the band through said slot; an outturned foot duced width portion of the band beyond said slot formin a tongue; said band and tongue being rolled and lapped upon itself to have-the tongue carried through from the inside to the outside of the band through said slot; an outturned foot on one end of the band adjacent an end of said slot; a bracket having a transverse slot therethrough; a foot on said bracket following substantially the curvature ofsaid rolled band; said tongue emerging from said band slot, from the inside to outside, and passing over the outside of said bracket foot and entering through said bracket slot and extending therebeyond under said bracket; an outturned clamp foot on said bracket at the end thereof toward which said tongue 'is directed; and means for pulling said band foot and saidbracket clamp foot one toward the other as means for reducing the eflec- *tive diameter of the rolled band; said bracket on one end of the band adjacent an end of said slot; a bracket having a transverse slot therethrough; a foot on said bracket following substantially the curvature of said rolled band; said tongue emerging from saidband slot, from the inside to outside, and passing over the outside of said bracket-foot and entering through said bracket slot and extending therebeyond under said bracketyan outturned clamp foot on said bracket at the end thereof toward which said tongue is directed; and means for pulling said band foot and said bracket clamp foot one toward the other as means for reducing the effective diameter of the rolled band.

2. A hose clamp comprising a band having a longitudinal slot through a length thereof; a reduced width portion of the band beyond said slot forming a tongue; said band and tongue being rolled and lapped upon itself to have the'tongue carried through from the inside to the outside of the band through said slot; an outturned foot on one end of the band adjacent an end of said slot; a bracket having a transverse slot therethrough; a foot on said bracket following substantially the curvature of said rolledband; said tongue emerging from said band slot, from the inside to outside, and passing over the outside of said bracket foot and entering through said bracket, slot and extending therebeyond under said bracket; an outturned clamp foot on said bracket at the end thereof toward which said tongue is directed; and means for pulling said band foot and said bracket clamp foot one toward the other as means for reducing the effective diameter of the rolled band; said bracket foot having a raised portion over said tongue thereunder, to form a tongue receiving channel.

3. A hose clamp comprising a band having a longitudinal slot through a length thereof; a refoot havin a raised portion over said tongue slot forming a tongue; said band and tongue being rolled and lapped upon itself to havethe tongue carried through from the inside to the outside of the band through said slot; an outturned foot on one end of the band adjacent an end of said slot; a bracket having a transverse slot therethrough; a foot on said bracket following substantially-the curvature of said rolled band; said tongue emerging from said band slot, from the inside to outside, and passing over the outside of said bracket foot and entering through said bracket slot and extending therebeyond under said bracket; an outturned clamp foot on said bracket at the end thereof toward which said tongue is directed; and means for pulling said band foot and said bracket-clamp foot one toward the other as means for reducing the effective diameter of the rolled band; said tongue having a preformed inwardly offset end portion extendingunder the bracket to form an abutting shoulder over the edge of said bracket slot.

5. A hose clamp comprising a band having a longitudinal slot through a length thereof; a reduced width portion of the band beyond said slot forming a tongue; said band and tongue being rolled and lapped upon itself to have the tongue carried through from-the inside to theend of said slot; a bracket having a transverse slot therethrough; a foot on said bracket following substantially the curvature of said rolled band; saidtongue emerging from said band slot, from the inside to outside, and passing over the outside of said bracket foot and entering through fective diameter of the rolled band and an abut'-' ment carried by said tongue to engage over the said bracket slot and extending therebeyond under said bracket; and outturned clamp foot on said bracket at the end thereof toward which said tongue is directed; and means for pulling said band foot and said bracket clamp foot one toward theother as means for reducing'the efedges of said bracket slot.

6. A hose clamp comprising a flexible hose encircling band; a bracket secured on one end of the band; a second bracket; a pressure member on said second bracket following substantially the curvature of said encircling band; said member having a transverse slot therethrough; a tongue end of said band inserted from the outer side of said member through said slot and extending eircumferentially therebeyond under the member; and means for pulling said two brackets, one toward the other, to reduce the effective diameter of the band.

7. A hose clamp comprising a flexible hose encircling band; a bracket secured on one end of the band; 'a second bracket; a pressure member on said second bracket following substantially the curvature of said encircling band; said mem- 'the member; and said member having a raised portion over that portion of the tongue extending thereunder.
